Asmaco 52 Grey Acrylic Duct Sealant

Key features include siliconized acrylic formulation for strong flexibility, asbestos-free composition, non-corrosive behavior on metals and plastics, low VOC content, no primer required, heat resistance, waterproof performance, quick drying, and long-lasting durability.

Use it for sealing joints and connections in air conditioning and ventilation ductwork, in both new installations and retrofit projects, especially in humid or damp environments where a waterproof seal is beneficial.

It can be applied directly to most surfaces without the need for a primer. It is non-corrosive and safe for metal and plastic surfaces commonly found in ductwork.

Prepare the surface by cleaning away dust and debris. Cut the nozzle to the desired bead size, apply a continuous bead around the joint, then smooth or tooling with a damp finger or sealant tool for a uniform seal. Allow to dry per ambient conditions; no primer required.

Asmaco 52 is quick-drying and dries rapidly at room temperature under typical humidity. Cure time depends on thickness and environmental conditions; the sealant will continue to cure over time to achieve full strength.
